'In these sixteen photographs are many deep echoes of experience from more than forty years in Yosemite Valley. Each represents, for me, a moment of wonder. These pictures are put together as a continual pattern of personal mood and response...This collection is, in a way, a personal autobiography in photographic images, the selection of which is based on emotional impulse and personal experience rather than on intellectual or historical judgement.

Both the grand and the intimate aspects of nature can be revealed in the expressive photograph. Both can stir enduring affirmations and discoveries, and can surely help the spectator in his search for identification with the vast world of natural beauty and wonder surrounding him - and help him comprehend man's continuing need for that world.'- Ansel Adams, 1960
